Monocots vs. Dicots Angela McFetridge [email protected] 7th grade Science SEEDS Monocot Protective seed coat Contain 1 cotyledon Endosperm: surrounds embryo As seed sprouts cotyledon stays below ground Absorbs nutrients from endosperm and transports to seedling Dicot Protective seed coat Contains 2 cotyledon Endosperm: surrounds embryo Before seed sprouts both cotyledon emerge from soil Absorbs & stores food from endosperm and transports to seedling Roots Monocot Fibrous roots: spread and branch out Anchor plant Provide loads of surface area to gather water and minerals Dicot One long, thick root Called taproots Small secondary roots grow from tap root STEMS Monocot Contains tubes that carry food downward and water and minerals upward Tubes are scattered throughout with no particular pattern Dicot Contains tubes that carry food downward and water and minerals upward Tubes are arranged in a ring pattern around center of the stem Leaves Monocot Veins run parallel in leaf Dicot Veins intersect and form a branching pattern in leaf Flowers Monocot Flowers have flower parts in 3’s Dicot Flowers are more varied, have flower parts in 2’s, 4’s, 5’s,…..
